Planning Permission Success Stories
Landmark Phosphate Mitigation Scheme Unlocks Stalled Development Projects
WCI’s innovative phosphate offset scheme is transforming development potential across Somerset. Following a groundbreaking agreement with Somerset Council, we’re delivering free sewage treatment plant upgrades that generate phosphate credits—unlocking planning permission for major residential, commercial, and infrastructure projects.
How WCI’s Phosphate Mitigation Scheme Works

Our nutrient neutrality programme addresses Somerset’s phosphate pollution challenge through strategic sewage treatment plant upgrades in four key catchment areas:
- River Tone catchment
- River Parrett catchment
- River Brue catchment
- River Axe catchment
By replacing outdated septic tanks with state-of-the-art sewage treatment plants at participating properties, we create measurable phosphate reductions.
These environmental improvements generate phosphate credits that enable developers to secure planning permission in nutrient-sensitive areas.
Major Planning Permissions Achieved Through WCI Phosphate Credits

Individual Development Plots Across Somerset
Beyond major projects, our phosphate mitigation scheme has unlocked numerous single-plot developments previously stalled by nutrient neutrality requirements—supporting local builders, developers, and Somerset’s housing supply.
Environmental Impact: Cleaner Rivers, Healthier Ecosystems
Current Programme Statistics
- 600+ property owners registered for free sewage treatment upgrades
- Four major river catchments receiving environmental improvements
- Measurable phosphate reductions across participating properties
- Multiple planning permissions unlocked for residential and commercial development
Triple Benefit Approach
Our phosphate offset scheme delivers value to three key stakeholders:
1. Environmental Protection Active pollution reduction supporting healthier river ecosystems and improved water quality across Somerset’s sensitive catchments.
2. Homeowner Benefits Qualifying property owners receive modern, compliant sewage treatment systems at zero cost, eliminating the expense of mandatory septic tank upgrades.
3. Development Enablement Developers gain access to verified phosphate credits, enabling planning permission in nutrient-neutral catchment areas without costly on-site mitigation.
The Future of Phosphate Mitigation in Somerset
With a substantial waiting list of registered property owners, WCI’s No Nonsense Nutrient Neutrality® scheme continues expanding. Each installation contributes to:
- Improved river water quality
- Protected aquatic ecosystems
- Unlocked development potential
- Economic growth across Somerset
- Peace of mind for homeowners facing septic tank replacement requirements
